Abstract
The invention discloses a scrambling transmission method and device. The method comprises the following steps of: generating sending information by a user terminal, modulating the sending information, and generating a data modulation symbol; scrambling the data modulation symbol by the user terminal by using the dedicated scrambling sequence of a cell; and sending the scrambled data modulation symbol in a time domain frequency spreading manner by adopting a DFT-S-OFDM (Discrete Fourier Transform-Spectrum-Orthogonal Frequency Division Multiplexing) transmission structure by the user terminal. The invention has the advantages of lowering the possibility of the mutual interference of user terminal data working on the same data between adjacent areas and improving the detection performance of uplink control signals.
